Well for the 1st time in a year I lock the doors. Using the power locks with the window down.so when I went to get back in the car I pull the lock up thru the window, and when I open the door the horn and light started beeping and I couldn't start the car. I had to undo the battery and reset it.my question is how do the alarm work and did my car come with a remote to arm and disarm from gm
